Google Map Center（Lat / Lng）问题

Question

The script that I use for google map in my site is

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js"></script>

I get the center from a hidden input by

var pos = $('#lat_lng').val();

in my console it pos print as 23.810332,90.41251809999994

The problem is if I use var myCenter=new google.maps.LatLng(pos); google map doesnot work but if I use

var myCenter=new google.maps.LatLng(23.810332,90.41251809999994);

It works fine. Where is the main problem? Thank you

Answer 1

主要问题是，这个new google.maps.LatLng从double类型中接受了2个参数，因此，当您传递Pos时，您会从string类型中传递一个参数，但是当您传递23.810332,90.41251809999994您会从double类型中传递两个参数

You need to use the correct constructor for the LatLng, have a look at the documentation .

 map.setCenter(new google.maps.LatLng(-34, 151));

Split your pos variable and then use each Lat and Long in the constructor as follows.

var pos_array = pos.split(",");
var myCenter=new google.maps.LatLng(pos_array[0], pos_array[1]);
